Restaurants and other food service establishments often make food items readily available to their customers via buffets, salad bars, breakfast bars, or similar set-ups allowing customers to serve themselves. To ensure the safety of certain food items, it is often necessary to ensure that the food items maintain a certain elevated temperature, and for other food items it is often desirable to serve the items at relatively warm or hot temperatures for the customer's enjoyment. Similarly, certain food items must be maintained at reduced temperatures for the safety of the food and/or for customer's enjoyment. At the same time, to further ensure sanitary conditions a “sneeze-guard” or “breath shield” type structure is often needed, if not required outright by health codes and regulations, between the customers and the food items to help prevent contamination of the food by bacteria or other germs.
While maintaining the sanitary condition of the food items, it is also desirable that the serving set-ups present the food items in a convenient, safe, and aesthetically pleasing manner. It is often desirable to fully display and illuminate the food items to increase their appeal to the customer, and therefore setups that partially or fully obstruct the customer's view of the food, for example through opaque components such as pan covers, or clear components that “fog up” and/or collect condensation from hot food items in a manner that obstructs a customer's view, may not be desirable even if they otherwise provide the necessary sanitation benefits.
To alleviate these possible inefficiencies, it may be desirable to provide food-serving systems and methods that maintain safe and sanitary conditions by heating food items and providing a barrier to prevent bacteria and germ contamination by customers, but do so in a manner that presents the food items in an appealing manner and allows customers to conveniently view and access any desired food items.
